AP5101SG-13

NOT RECOMMENDED FOR NEW DESIGN CONTACT US AP5101 1.5A STEP-DOWN CONVERTER WITH 1.4MHZ SWITCHING FREQUENCY Description Pin Assignments The AP5101 is a current mode step-down converter with a built-in power MOSFET to enable smallest solution size power conversion. ( T o p V ie w ) With the low series resistance power switch, it enables a constant output current of up to 1.5A over a wide input supply range. The load and line regulation has excellent response time over the operating input voltage and temperature range. SW 1 8 GND IN 2 7 BST The AP5101 is self-protected, through a cycle-by-cycle current limiting algorithm and an on chip thermal protection. The AP5101 will provide the voltage conversion with a low count of widely available standard external components. EN 3 6 COMP GND 4 5 FB S O -8 The AP5101 is available in SO-8 package.
